DVI
Digital Visual Interface; a digital interface specification created by an industry consortium, the Digital Display Working Group.
This universal standard for connecting flat panel monitors is also used for data projectors, plasma displays, and digital TVs.
Using a DVI connector and port, a digital signal sent to an analog device is converted into an analog signal (if the device is
digital, such as a flat panel monitor, no conversion is necessary). There are three different DVI configurations: DVI-A for analog
signals, DVI-D for digital signals, and DVI-I (integrated) for both analog and digital signals.
DTV
Digital television is a generic term that refers to all digital television formats, including high definition television (HDTV) and
standard definition television (SDTV).
HDMI
High Definition Multimedia Interface. USB-like digital video connectivity standard designed as a successor to DVI. Transmits
both digital audio and video signals and incorporates HDCP digital copy protection.
Interlaced scanning
Scanning method used by the 1080i HDTV format. As opposed to progressive scanning, in which the CRT's electron beam
scans or “paints” all lines at once, interlaced scanning TVs paint odd-numbered lines in succession, then go back and fill
in the remaining even-numbered lines. This method is more prone to artifacts and less stable than progressive.
Progressive scan
A method of displaying images on a CRT monitor or a high definition TV in which all the lines of a picture are drawn in one
quick burst, from left to right and from top to bottom. Compare this to interlacing, in which every other line is displayed in
two successive swoops to form a complete picture.
SDTV
Standard definition television. Digital television format that includes 480-line resolution in both interlaced (480i) and
progressively scanned (480p) formats; offers discernible improvement over conventional analog NTSC picture resolution,
with less noise; similar to DVD or satellite TV quality but not considered high definition.
Widescreen
An image with an aspect ratio greater than 1.33:1, or a picture wider and narrower than a traditional television image.
Typically refers to TVs in the 16:9 aspect ratio.
Y Pb Pr
Luminance, and two chrominance channels of blue minus luminance and red minus luminance. This technical shorthand for
component video is also written as Y Cb Cr
( or Y R-Y B-Y).
